Hi..

I don't know of any downloadable info for you, but it is perfectly normal for the compressor to run/ cycle down to an ambient temperature of 4-5C, after which the low pressure switch will prevent the compressor from running.

The VW Climatronic system will take the chilled air and pass some of it through the heater matrix and will then blend the chilled air with the heated air to achieve the desired temperature...

To turn off the AC compressor totally, just hit the "Econ" button

Which model and year is your Passat? as I suspect that the current model will probably use the Denso clutchless compressor, but I have not worked on one of these yet

Sounds like a question for TDI. Look him up in members area.
